How to Reset the MCM
You can reset the motor control module (MCM) using either of these two methods
Scheme 371
- Use the HDS to clear the MCM memory. See the HDS user's manual for specific instructions.
- Turn the ignition switch OFF, and remove the No. 18 BACK UP (7.5 A) fuse (A) from the under-dash fuse/ relay box (B) for 10 seconds.
Note. If the MCM has been reset, the IMA battery level indicator (BAT) will not indicate the state of charge when the engine is started. Refer to " HOW TO END A TROUBLESHOOTING SESSION " to set the correct state of charge. Removing the No. 18 fuse may also reset the ECM. Do the ECM idle learn procedure (see ECM IDLE LEARN PROCEDURE ) after resetting the ECM. CVT: Removing the No. 18 fuse may also reset the TCM. Do the start clutch calibration procedure (see START CLUTCH CALIBRATION PROCEDURES ) after resetting the TCM.
